SHINGLE-CAB.

Specification of Letters Patent.

Patented J an. 30, 1917.

To all whom it may concern:

Be it known that I, Lnwrs H. THOMPSON, a citizen of the United States, residing at California, in the county of Moniteau and State of Missouri, have invented certain new and useful Improvements in Shingle- Cars; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to shinglecars used for supporting shingles upon a roof skeleton during the construction of a building and the primary object of the invention is the provision of a car as specified which is supported upon the sheathing of the roof skeleton by rotatable rollers to permit of the free movement of the car over the roof frame.

Another object of this invention is the provision of horizontally rotatable disks carried by one end of the shingle car and suspended beneath the under surface of the same, for engagement with the edges of the sheathing strips which prevents the car from sliding down the incline of the roof.

A still further object of the invention is the provision of pivoted standards connected to the sides of the shingle car to facilitate the mounting of bundles of shingles thereupon.

With the foregoing and other objects in view this invention consists in such novel features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings and claimed.

In describing the invention in detail reference will be had to the accompanying drawings wherein like characters designate like or corresponding parts throughout the several views, and in which Figure 1 is a perspective view of the improved shingle car showing the same upon a fragment of a roof, and Fig. 2 is a cross sectional View through the car showing the same attached to the sheathing strip. Fig. 3 is a fragmentary perspective View of the shingle car showing the upper end of the same.

Referring more particularly to the drawings, 1 designates a fragment of a roof which is composed of the rafters 2 and sheathing strips The shingle car which is provided for supporting a bundle of shingles upon the roof'skeleton preparatory to the attaching of the shingles to the sheathing strip is composed of side and end strips 4 and 5 respectively, which are secured together to form a rectangular frame. The end strips 5 have the ends of a rod 6 journaled therein, which rod extends entirely across the length of the shingle car and have standards 7 mounted upon their outer ends, which standards are positioned exteriorly of the ends 5 of the frame. The standards 7 are pivotally mounted upon the ends 5 of the frame of the shingle car so that they may be moved independently of each other, for bending downwardly to permit of the placing of a bundle of shingles (not shown) upon the car.

The ends 5 of the frame of the car have the shafts 8 and 9 of the rollers 10 and 11 journaled therein, whereby the rollers 10 and 11 are rotatably supported interiorly of the frame of the car as is clearly shown in Fig. 1 of the drawings. The rollers 10 and 11 extend below the lowermost edges of the sides 4: and ends 5 of the frame and rest upon the sheathing strips 3 so as to permit of the free movement of the shingle car along the length of the sheathing for conveniently placing the shingles for nailing to the sheathing strip by a carpenter.

The upper end 5 of the car has a metallic strap 12 secured thereto and extending downwardly therefrom. The metallic strap 12 has portions thereof bent downwardly away from the under surface of the upper end 5 of the car for forming saddles, as is clearly shown in Figs. 2 and 3 ofthe drawing. The upper end piece 5 of the shingle car has pins 14 secured thereto and extending downwardly therefrom, which pins have disks 15 rotatably mounted thereupon. The pins 14: extend perpendicularly through the saddles formed by the downwardly bent portions of the strap 12. The

disks 15 have their peripheries sharpened for engagement with the edges of a sheathing strip 3 for holding the shingle car upon the roof skeleton and preventing the same from sliding downwardly along the incline of the roof.

' In reducing the invention to practice certain minor features of construction, combination and arrangement of parts may necessitate alteration to which the patentee -is entitled provided such alterations are comprehended Within the scope of What is claimed.

WVhat is claimed is In a shingle ear structure, a rectangular frame composed of end and side strips, shafts rotatably carried by the end strips of said frame, rollers mounted upon said of one ofjsaid end strips and having saddles formed therein, vertical pins carried by said saddles, disks rotatab'ly carried by said pins, said disks hav ng their peripheries sharpened for engagement with the edge 'of a roof sheathing strip to prevent downwardly sliding movement of said frame, said saddles forming guards and supports for said vertical pins.

In testimony whereof I affix my signature in presence of two Witnesses.
